The Study On Evaluation System Of Ecological Landscape Forests In Coastal Area Of Yanshan East

This article refers to the massive correlation literature on the field survey to Qinhuangdao's Tang River park landscape,The evaluation system of ecological landscape forests is established and study on the Qinhuangdao' outer ring road based on The evaluation system of ecological landscape forests.Using scenic beauty evaluation to evaluate ecological landscape forests;Using AHP model to evaluate landscape effects; Using landscape ecology index to evaluate landscape stability;Using "the botanical garden benefit reckoning formula" to evaluate the the carbon oxygen balance benefit analysis,the SO₂benefit analysis and the storage benefit analysis.From this draws the following conclusion:1.Scenic Beauty Evaluation results on Qinhuangdao' outer ring road:Through Scenic Beauty Evaluation analysis,the biggest contribution to the landscape obtains life form,flowers ratio,canopy density,turf density,and so on.The Independence of the 4 factors are good,using the regression analysis method to establish the following model, Y=-5.086+1.123X₁+0.145X₂-0.062X₃+0.239X₄,X₁represents life form,X₂ represents flowers ratio,X₃ represents canopy density,X₄ represents turf density,and Variance analysis result indicated the linear correlation significant between Y and X₁,X₂,X₃, (P=0.000＜0.01).Therefore,various factors and Scenic Beauty Evaluation has extremely significant relevance.2.Evaluate results on species diversityThe evaluation results show that,synthetic graded value of landscape effect on Qinhuangdao' outer ring road is between 7.9-8.5(the full score was 10),the landscape effect is good.In plant landscape each kind of combination take the type place 1,2,5 landscape effect as "good",the type place 8 always grade is relatively low,manifests the seasonal aspect landscape the tree seed choice to be few and must further afforest the beautification.3.landscape stability forecasting result on Qinhuangdao' outer ring roadThe outer ring road landscape varying degree receives some type the control,the green space landscape type area distribution is not balanced,the landscape type is relatively non-uniform in the region assignment degree,the green space landscape's function is relatively low.
